WHY DOES EMPEROR CHARLES CALL V2 BIG BROTHER IN CODE GEASS R2?
because v2 is his elder brother, who has made contract with an unknown immortal and then take the immortal’s code and becomes a code bearer / immortal, just like in C2’s case… he became an immortal or code bearer when he was a kid so, he can’t grow up since the immortal stops aging when they get the code..
